' This invention relates to wringers for washing machines. 1

One of the objects of the invention is in the provision of a safety wringer for wash- 5 ing machines.

Another object'is in the provision of a wringer for washing machines, the same being of a safety type and including a moving belt portion co-operating with the roll members in such manner that the clothes content may be placed upon the belt portion and carried between the rollers without the neces sity of the operator forcing the clothes content between the rolls.

Still another object lies in the provision of a safety wringer mechanism including pressure rolls and a belt portion, the upper end of said pressure roll. being fashioned for movement from one side of the pressure roll to the other. M

A further object lies in the-.-provision of a safety wringer mechanism wherein there 1s a power roll, a belt member cooperating with the power roll upon which the clothes con.- tent is adapted to be placed prior to the wringin action, and a pressure roll normally dispose laterally of the power roll but adapted for movement to a position on the opposite side of the power roll to permit 3 the operator to accomplish a reverse wring in operation.

%ther objects will appear in the following specification taken in connection with the annexed drawings, in which- Fig. 1 is a plan view' from safety wringer; and

Fig. 2 is an end elevation thereof.

Before referring specifically to the drawings, it might be said that there is considerable development work in the washing machine industry tending towards safer wringer mechanism. The well known wringeris undoubtedly very eflicient as far as the wringing operation is concerned. However, when one considers that so many devices have been provided for relieving the pressure between the rolls when the operator has her finger,

hand or arm caught in the wringer, it is apparent that accidents do happen to wringers and that any device which goes further than above of the the safety release mechanism merits consideration.

The present applicant has-been activeinthe form portion, which in turn carries the clothes content between the rolls.

There is no necessity in this type of wringer for the operator to force the clothes :into the bite of the rolls, which obviously causes practically all of the accidents to women-,- who, it must be admitted, are in practically'every instance,

the operators 'of washing machines and wringing devices thereon.

In the drawings, applicant has "disclosed a simple wringer device which as far as structural make-up is concerned, would not materially change theappearance of a washing machine, and as a matter of fact, due to its low height, would probably enhance the general appearance, besides creating a. much more eflicient wringer, as far as the safety element is concerned, and there is no question but that the general public is at this date much concerned with this feature of safety.

Applicant provides a wringer frame comprising end pieces l0 and 141 and a bottom plate 12 acting as a guide for a driven belt member and connecting the said end pieces. This bottom plate has its edge portions curved as at 13 and 14 and also cut away in the plural manner shown at 15, for the purpose of carrying the plural belt members later to be described.

Cross bars 16 and 17 project between the side-plates at each side of the wringer in a manner to support the wringer, as well as the end portions which operate also as catch members for the pressure roll'. A power roll 18 is disposed in the wringer frame, the same having the power shaft 19 disposed centrally thereof and projecting through the side plate 11 in a manner to be-connected to the driving means for the wringer and being so conventional as to obviate the necessity of description. 1

The power shaft v19 is carried in bearin members 20 and 21, which in turn are carriec l in supporting brackets 22 and 23 formed either as a part of the end plates or secured thereto in any manner-desired. A plurality of strips or belts 24 surround the power roll and the bottom plate 12 of the wringer frame, said belts being guided by the cut-away portions 15 previously described, and passing smoothly about curved portions 13 and 14 of the plate 12. Obviously, these plural strips, which actually make up one belt member, may rotate in eitherdirection, the same being controlled by movement of the power roll. A pressure roll. is shown at 25, the shaft 26 thereof having its end portions carried in plural bearings 27 slidably mounted in the stamped 1 metal pressure roll framing member 28. This pressure roll. frame not only carries the coil tension springs 29 for the pressure roll, which normally tends to force same against the power roll, but also said frame is adapted to. rotate upon the previously described stamped metal brackets 22 and 23, which support the bearing for the shaft 19 of the power roll. In other words, the framing for the pressure roll may be moved at 'willrfrom one side or the other of the power roll.

v 'vided for adjusting the tension of coil springs 29 used to apply pressure of roll '25 against power roll 18. A pin 38 is also provided to act as a stop, for-bearing 27 when tension is released from pressure against the power roll.

Means for moving the pressure roll from one side to the other of the power roll to accomplish reverse wringing operation, is

. provided in the manually controllable lever 30, the'same comprising handle portion. 31,

l the portions '32 of which lie fiat against the upper side of the frame for the pressure roll,

said portions being carried in a rotatable manner :by clips 33 upwardly projecting therefrom and formed as a part of the ham-- ing member, the outer 'ends 34r of the bar 30 being offset in such manner as to be capable of movement within the latch portions 35 formed in the ends 10 and 11 of the wringer frame, and when in this position operating to holdthewringer frame for the pressure roll in a fixed position as respects the power roll.

' It is apparent also that when said bar 30 is roll, due to the sliding connection between Set screws 36 and block 37 have been pro- I the frame for the pressure roll and the bearings for the power roll.

- 'As far as the operation of the present I: wringer is concerned, the actual wringing operationis accomplished by the movement 'of the clothes content between the power and pressure rolls, ust as in any of the Well known wvringer devices. However, the movement of the power roll transmits similar movement to the belt member, made 'up ofthe plural strips, and-the operator may in this instance place. the clothes upon this movable belt, which in turn carries the clothes content be-, tween the rolls and obviates the necessity of forcing the clothes into the bite of the rolls.

This, device also operates to prevent the clothes from continuing around the pressure a swung about from one position to another to take care of the various wash and rinse tubs about the washer, the operator hasmerely to move the handle '31 to release the ends 34 from the latch portions 35 and thereupon swing the entire pressure roll and framing portion to an opposite osition, thereupon latching same in exactly t e same manner.

It is apparent that the present safety wringer has also the advantage of any of the well known safety devices, inasmuch as same has'a safety release. means for-the pressure roll, it bein apparent that in case the opera; tor should iave her finger or hand-can ht between the rolls,although such a condition could hardly be possible with the present' wringer-nevertheless, even in such instance, all that the operator would need to do'would be to move handle 31 to release osition, which would automatically release t e pressure between therolls.

WhatIclaimisr Y I 1.' In a wringerdevice the combination of a wringer frame, a power roll, a pressure roll, means for latching thepressure roll in operac tive position on either side of the power roll, said positions being substantially symmetrical with respect to a vertical plane through the horizontal-axis'of the power roll, a guide member spaced from and'below the power rolland projecting laterally an equal distance beyond each side of a vertical plane in which the axis of the power roll lies, and a belt member driven by said power roll and passing about the guide member, said belt member cooperating with the roll members -to carry the clothes content into the bite of the rolls when. 136 l the pressure roll is in operative position on either side of the ower roll.

2. In a wringer evice, a power roll, a pressure roll shiftable from one operative position in pressure relation with the power roll to a second operative position in pressure relation with the power roll, belt guiding means spaced from the power roll, a belt trained about the ower roll and the belt guiding means, said guiding means extending on opposite sides of, per endicular to, and equal distances from, a p ane in which the axis of the power roll lies, said plane bisecting the angle formed by two planes formed by passing through the axis of the power roll and the axes of the pressure'roll in both of its operative positions.
